self_destruct_sequence

Runs for as long as the station self-destruct terminal is counting down. Owns the announcement, the point of no return, and the secondary detonations after it. The detonation itself belongs to the terminal's own timer, which is pinned to SELF_DESTRUCT_DURATION.

Vars
announcement_channel	Reserved sound channel, so an abort can silence the announcement mid-sentence.
past_no_return	TRUE once the announcement has stated that cancellation is off the table.
reddened_areas	Station areas we put into their fire alarm state, so an abort can put them back.
served	Clients already hearing the announcement, so we never restart it under one that has it.
start_time	world.time the sequence began. Every other time here is an offset from this.
terminal	The terminal counting down. We do not outlive it.
Procs
broadcast_announcement	Sends the announcement out. Defaults to everyone in the round, which is what the first broadcast wants.
build_announcement	The announcement, seeked to however far into the sequence we already are.
detonate	Fires the terminal one cinematic intro before the announcement ends, so the 3-2-1 counts onto zero and the blast lands on the end of the track instead of after it.
elapsed	Deciseconds since the sequence began.
on_client_gone	A client that leaves takes its sound channels with it, so let a reconnect be served fresh.
on_player_login	Drops anyone entering the round mid-sequence in at the right point in the track.
on_terminal_deleted	No terminal means no bomb left to detonate.
pass_point_of_no_return	The announcement has just said cancellation has expired, so make that true.
pick_blast_site	Weighted towards somebody who will actually witness it, since a blast nobody saw may as well not have happened.
pick_site_near_crew	A turf a room or two from somebody still aboard. Null if there is nobody left to play to.
quiet_blast	An explosion sound built to lose. Nothing else sets priority, so these sit below every other sound.
redden_lighting	Flips every station area into its fire alarm state, which is what turns the lights red.
schedule_next_blast	Queues the next secondary detonation, tightening the interval as the terminal counts down.
secondary_detonation	One of the station's own systems letting go. Light impact only, so it hurts without reliably killing.
silence_announcement	Cuts the announcement off everywhere.

Var Details

var
announcement_channel

Reserved sound channel, so an abort can silence the announcement mid-sentence.

var
past_no_return

TRUE once the announcement has stated that cancellation is off the table.

var
reddened_areas
– /list/area

Station areas we put into their fire alarm state, so an abort can put them back.

var
served
– /list/client

Clients already hearing the announcement, so we never restart it under one that has it.

var
start_time

world.time the sequence began. Every other time here is an offset from this.

var
terminal
– /obj/machinery/nuclearbomb/selfdestruct

The terminal counting down. We do not outlive it.

Proc Details

proc
broadcast_announcement
(/list/players)

Sends the announcement out. Defaults to everyone in the round, which is what the first broadcast wants.

Skips anyone already hearing it. Sound channels belong to the client rather than the mob, so changing bodies does not interrupt playback - re-sending would only re-seek the track, which is audible, and dying to a secondary detonation is a very common way to change bodies in here.

proc
build_announcement
()

The announcement, seeked to however far into the sequence we already are.

proc
detonate
()

Fires the terminal one cinematic intro before the announcement ends, so the 3-2-1 counts onto zero and the blast lands on the end of the track instead of after it.

proc
elapsed
()

Deciseconds since the sequence began.

proc
on_client_gone
(/client/gone)

A client that leaves takes its sound channels with it, so let a reconnect be served fresh.

proc
on_player_login
(/datum/source, /mob/player)

Drops anyone entering the round mid-sequence in at the right point in the track.

proc
on_terminal_deleted
(/datum/source)

No terminal means no bomb left to detonate.

proc
pass_point_of_no_return
()

The announcement has just said cancellation has expired, so make that true.

proc
pick_blast_site
()

Weighted towards somebody who will actually witness it, since a blast nobody saw may as well not have happened.

proc
pick_site_near_crew
()

A turf a room or two from somebody still aboard. Null if there is nobody left to play to.

proc
quiet_blast
(blast_sound)

An explosion sound built to lose. Nothing else sets priority, so these sit below every other sound.

proc
redden_lighting
()

Flips every station area into its fire alarm state, which is what turns the lights red.

proc
schedule_next_blast
()

Queues the next secondary detonation, tightening the interval as the terminal counts down.

proc
secondary_detonation
()

One of the station's own systems letting go. Light impact only, so it hurts without reliably killing.

proc
silence_announcement
()

Cuts the announcement off everywhere.
